FIREARM.

Application led November 8, 1923. Serial No. 673,444.

(FILED UNDER THE ACT 0F MARCH 3, 1883, 22 STAT. L., 625.)

To all whom t may concern:

Be it known that I, SAMUEL WILEY, a citizen of the United States, and a resident of Metuchen, county of Middlesex, and State of New Jersey, have invented an Improvement in Firearms, of which the following is a specification.

The invention described herein may be used by the Government, or any of its oficers or employees in prosecution of work for the Government, or by any other person in the United States, without payment to me of any royalty thereon, in accordance with the act of March 3, 1883.

The present invention relates to firearms.

The primary object of my invention is the provision of a firearm in which the gases generated on firing one projectile therefrom are utilized to project simultaneously therewith a diderent caliber projectile.

A further object is the provision of a firearm having a double barrel which may be employed to project simultaneously two different sized projectiles or may readily be converted into a single barrel service piece.

With the foregoing and other objects in view, my invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

A preferred embodiment of my invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a plan view of my firearm;

Fig. 2 is a view in side elevation, with parts broken away;

Fig. 3 is a detail sectional view of the butt plate;

Fig. 4 is an enlarged detail sectional view of a portion of the bore;

Fig. 5 is a section on the line 5-5 of Fig. 2; and

Fig. 6 is a detail showing the piece used for converting the firearm into an ordinary service weapon.

Referring to the drawings by numerals of reference:

I have shown at 5 a firearm equipped with the ordinary iring mechanism 6 and having the usual stock 7 This firearm is provided with a chamber 8 adapted to receive an ordinary service cartridge.

Threaded or otherwise secured to this chamber and to the stock of the firearm is a bore chamber 9 separated by a dividing wall which is preferably formed integral with the bore chamber into an upper barrel 10 adapted to serve as a passageway for the ordinary service projectile and a lower barrel 11 adapted to serve as a passageway for a projectile of a different caliber such as a grenade.

A passageway 12 between the two barrels permits the gases generated on ldischarge of the service projectile to pass freely into the lower barrel 11 propelling the projectile contained therein from the piece.

The operation of my device is as follows:

A service cartridge is placed in the chamber 8 while a grenade or other suitable projectile is placed in the bore 11. When the piece is fired the gases generated by the propellant in the service cartridge serve a double purpose; namely, to propel the bullet from the bore 10 and because the| bullet in its passage through that barrel acts as an obturator to propel the other projectile from the barrel 11, the gases generated upon firing the piece passing through the passageway 12 and forcing the projectile contained in the lower barrel out of the piece.

The fire arm, which forms the subject of this invention, may be readily converted into the ordinary service weapon by inserting a plate such as the plate 13 into the passage way 12 formed in the dividing wall between the two barrels. This is done by turning the piece upside do-wn dropping the plate 13 into the lower barrel 11 removing the plug 14 from the gun h-arrel and inserting a too-l into the opening normally closed by the plug to bring the plate 13 into its proper position. With the plate 13 in proper position the piece may be readily used as a single barreled service fire arm.

To absorb the extraordinary shocks caused by the explosion necessary to expel both projectiles from the piece the butt may be provided with rubber cushions 16, which are secured by bolts 17 between the butt plate 18 of the rie proper and a protecting plate 19. Sockets 20 are formed in the butt to permit movement of the bolts due to the resiliency of the rubber cushions.

While my device is primarily intended for use as a grenade discharger, it is by no means limited to this use. The projectile to be fired from the lower barrel may be of any desired size and the barrel itself may be of any desired diameter-being varied according to the caliber of the projectile which it is desired to project from the same.

As illustrated, my invention has been applied to a service rifle, it is by no means intended to limit the same to this use inasmuch as the usual service pistol may be altered in the manner described above vto lire simultaneously two different caliber projectiles.

I claim:

l. In a fire arm, a bore chamber formed in one piece, a dividing wall integral with the bore chamber and serving to separate the bore chamber into a pair of barrels7 said dividing wall formed with an opening whereby the barrels may communicate with one another, one vof the barrels adapted to contain a service projectile and serve as a passageway therefor, the other of said barrels adapted Vto contain a second projectile and serve as a passageway therefor, whereby the service projectile while traversing its barrel upon the firing of the piece, acts as an obturator and checks the gas-es generated by firing, the gases collecting in the second barrel to propel the projectile therefrom, and means adapted to be removably positioned in the opening in the dividing wall whereby the fire arm may be converted into an ordinary service piece.

2. In afire arm, a. stock, firing means secured to the stock, a cartridge chamber secured to the stock, a bore chamber formed in one piece and secured to the cartridge chamber and adapted to butt against the forward end of the stock, a dividing wall integral with the bore vchamber and serving to separate the bore chamber into a pair of barrels, said dividing wall formed with an opening whereby the barrels may communicate with one another, one of the barrels adapted to contain a service projectile and serve as a passageway therefor, the other of said barrels adapted to contain a second projectile and serve as a passageway thereor7 whereby the service projectile while traversing its barrel upon the ring of the piece acts as an obturator and checks the gases generated by firing, the gases collecting in the second barrel to propel the projectile therefrom.

3. In a fire arm, a stock, firing means secured to the stock, a cartridge chamber secured to the stock, a pair of intercommunieating barrels secured to the cartridge chamber and adapted toy butt against the forward end of the stock and having a common dividing wall adapted to serve as the lower wall for the upper barrel and the upper wall for the lower barrel, one of said barrels adapted to contain a service projectile and serve as a passage way therefor, the other of said barrels adapted to contain a second projectile and serve as a passageway therefor, whereby the Service projectile while traversing its barrel upon the firing of the piece acts as an obturator and checks the gases generated by firing, the gases collecting in the'second barrel to pro-pel the proj ectile therefrom.
